How do you specify dowel holes Autodesk Community

2016 11 21 nbsp 0183 32 For example for a 1 2 quot slip fit hole all the clearance fit tolerances have an MMC end at nominal which for a dowel pin would allow the hole to be a press fit since dowels are typically 0 0002 quot over the nominal I can t have a clearance hole spec that allows for a 0 5000 quot hole Currently I normally would manually call out a hole that s 0 501
